Citrix servers booting into Maintenance Mode after power outage

[Marc Rosenthal1709155479]

Hello. I have several hosts in a pool that had shutdown unexpectedly after power had gone out and the the UPS exhausted it's backup power.  When power was restored, the hosts all booted into Maintenance Mode. This has happened more than once. Since the domain controllers and DHCP server are virtual and didn't start because the hosts were in Maintenance Mode, no one could get their address if DHCP. Is there a way to have the hosts boot to the state they were in prior to power going out?

 

Thanks for any help you can provide.

This sort of thing should work. I've done it before but its been a while. But more importantly you need protected power 

on your hosts. Loss of power can corrupt hosts and/or VM's and you will be forced to restore your VM's from backup.

Lots can g wrong when the power fails, including disk corruption and with it, the loss of settings, VM data, etc. It's always a good idea to have backups of everything, including the server/pool metadata, VM storage and settings, network and storage configurations, etc.
